If it's running good and smooth I wouldn't do anything but that governor. Unless you want to spend some money....call Plowman's Carts. You can get a performance clutch kit, carb jets, and performance muffler and it will run really good and have lots of low end grunt. Probably around $400 or so. Other than that you are looking at lift kits, tires, paint, roll bars, stuff like that. These are fun carts.
